What makes it play/not play?
E.g. from a clean boot does it play? Does playing a different file make it play/not play?

When I boot the machine it plays only audio no matter which .mov file I select.
If I reboot XMBC and try again it plays. It could be that there is a problem with memory.
I just used the default configuration and overclocked to stable values but with or without overclock it behaves the same.

Can you please post your config.txt file?
Maybe the memory settings create the problem for me.
